Definitions

  • This invention concerns pipe couplings. If a pipe is to be cast into a concrete wall or floor, formwork for the casting has to be altered to allow the pipe to pass through. That is time consuming and hence costly. Furthermore, the altered formwork will be less re-usable. Additional expense arises in supporting the pipe temporarily during casting. Alignment of the pipe is time consuming and difficult and often a source of error.
  • An object of this invention is to provide a way of casting pipes into concrete that avoids or at least mitigates against one or more of the above-mentioned disadvantages.
  • a pipe coupling which coupling may itself be cast into concrete and to which one or more pipes may be coupled.
  • a preferred pipe coupling of the invention comprises a sleeve having an external flange for attaching the coupling to formwork for concrete casting.
  • the flange may be integral with or separable from the sleeve.
  • the external flange may be spaced inwardly from one end of the sleeve, whereby a collar or the like may be connected thereto by means for drawing the collar and flange towards each other for urging a sealing ring into sealing contact with a pipe in or through the sleeve.
  • the sealing ring is in a recess of the collar and is compressed between the collar and an end of the sleeve. In another preferred embodiment, the sealing ring is in an annular recess of the sleeve end and is compressed therein by the collar.
  • an external flange may be at the end of the sleeve for direct connection of a flanged pipe, valve or other piece of pipework to the coupling by any suitable means such as by bolts or by welding.
  • Pipe couplings of the invention may be provided for single pipe coupling ie., for one side of a concrete wall or floor, or may be provided for coupling to opposite ends thereof.
  • the sleeve preferably increases in internal diameter from its intended outer end.
  • the sleeve preferably increases in internal diameter from its ends towards its mid-region. That increase in internal diameter provides some tolerance in alignment of a pipe to be inserted into the coupling.
  • the external flanges of the couplings of the invention may be tapped for receiving bolts or the like for attaching the couplings to concrete casting formwork.
  • packing pieces may be required between the flanges and the formwork.
  • the external flanges ⁇ may be provided with anchorages, such as anchor bolts, preferably on their inner faces.
  • the sleeves of the couplings of the invention may be provided with one or more external puddle flanges. Furthermore, the sleeves may be stepped to accommodate pipes of different diameters at opposite ends of the couplings.
  • the couplings of the invention may be fixed to formwork for concrete casting in any desired position. Then after casting and removal of the formwork, pipes may be coupled to or through the coupling and sealed about their circumference.
  • Figure 2 is a section through a second coupling according to the invention in situ.
  • Figure 3 is a section through a third coupling according to the invention in situ.
  • a first coupling 10 is shown cast into concrete 12.
  • the coupling 10 comprises a sleeve 14 which has an increased internal diameter in its mid- region compared to its ends. Spaced in from each end the sleeve 14 has a flange 16.
  • Each flange 16 is tapped on its outer face at 17 to receive bolts 18 for a collar 20 which has an annular recess 22 for a rubber or like sealing ring 24 such that, as tightening the bolts, the collar 20 is urged towards the flange 16 to trap and compress the sealing ring between the collar and the end of the sleeve 14.
  • To the inward face of each flange 16 are secured anchor bolts 26.
  • the coupling 10 is cast into the concrete by first fixing to one side of shuttering for casting a ring of material, such as plywood, of slightly larger external diameter than the coupling flange and shaped to give a chamfered outer edge shape as shown.
  • the sleeve is then fitted to the shuttering with its flange up against the plywood ring and the same operation repeated for the opposite shuttering.
  • the tapped holes 17 in the flanges 16 may be used for bolts to fix the flanges to the shuttering.
  • the shuttering is removed to leave the flanges 16 exposed.
  • the pipes 30 to be fitted to the coupling can then be packed into position and the sealing rings and collars fitted and tightened.
  • the pipes 30 do not have to be fitted exactly in line, as the sleeve has space for the pipes to be out of line but still sealed effectively.
  • a single pipe length may be fitted through the sleeve.
  • the sleeve 14 has the same diameter at each end. However, it is possible for the sleeve to be stepped for coupling pipes of different diameter. In addition, the sleeve may be provided with an external puddle flange.
  • a pipe coupling 40 is shown which is intended for connection to a flanged pipe or valve at one end as well as for pipe coupling at its other end in the same way as the coupling of Figure 1.
  • the coupling 40 comprises a sleeve 42 having a larger diameter at its mid-region than at either end, which provides a degree of tolerance for fitting a pipe 43 into the coupling.
  • the sleeve 42 has a flange 44 spaced inwardly from one end thereof and a flange 46 at the other end thereof.
  • the flange 44 is tapped on its outer face at 48 to receive bolts 50 for a collar 52 which has an annular recess 54 for a sealing ring 56 which is trapped between the collar and the end of the sleeve 42.
  • the flange 44 may also have anchor bolts 60 on its inner face.
  • the flange 46 is intended for direct coupling of a flanged pipe or valve in a conventional manner, such as by means of bolts or by welding.
  • the coupling 40 is cast into concrete 62 in a similar way to the coupling 10 except that the flange 46 is attached directly to shuttering so that after casting and removal of that shuttering,, the flange 46 is flush with the concrete.
  • the sleeve 42 may be stepped for accommodating pipes of different diameter at opposite ends and puddle flange may be provided on the outer surface of the sleeve.
  • a coupling 80 is shown that is for use on one or both faces of a wall or floor.
  • the coupling 80 comprises a sleeve 82 having a widening cross-section from one end to the other.
  • the sleeve 82 has an external flange 84 which is tapped at 86 for bolts 88 for securing a collar 90 to the flange.
  • the collar has an annular recess 92 for a sealing ring 94 which in use is trapped between the collar 90 and the end of the sleeve 82. The sealing ring when compressed between the collar and sleeve end expands inwards to seal against pipe 96 inserted into the coupling.
  • the coupling 80 is cast into concrete in a similar way to the coupling of Figure 1 of the accompanying drawings.
  • Anchor bolts 100 may be provided on the inner face of the flange 84. Because the sleeve diverges internally from its outer end, the pipe 96 does not have to exactly in line with the opening through the concrete but may be a few degrees off in any direction.
